RAGCUTTIN G MACHINE.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed March 30l 1907. Serial No. 365.515.

To'aZZ 'whom it may concern:

Be it known that I, GORDON W. HALL, a resident of Lockport, in thecounty of Niagara and State of New York, have invented certain new anduseful Improvements in Rag-Cutting Machines; and I do hereby declare thefollowing to be a full, clear, and eX- act descri tion of the invention,such as will enable otiiers skilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in rag-cutting machines and moreparticularly to the cutter cylinder or head,the obj ect of the inventionbeing to provide simple and efiicient means for rmly and quicklysecuring the knives to the cutter head or cylinder.

With this object in view, the invention consists in certain novelfeatures of construction and combinations and arrangements of parts ashereinafter set forth and pointed out 1n the claims.

In the accompanying drawings; Figure 1 is a perspective view showing acutter head or cylinder embodying my improvements; Fig. 2 is atransverse sectional view, and Fig. 3 is a detail view of the bindershoe.

1 represents a cutter head orcylinder provided at its ends with annularflanges 2, and having suitable sockets for the reception of the knives3, only one of which latter is shown in the drawing. The head orcylinder 1 is provided with several series of lugs 9 (one series foreach knife), and these lugs are made with concave seats 4 to formbearings for conical internally threaded nuts 5. These conical nuts alsohave bearings in concave seats 7 on a binding shoe 8 and the latter isadapted to bear against and bind the knife in place. The nuts 5 are thuslocated between the lugs 9 on the head 1 and the binder shoe 8. Threadedstuds 10 are secured to the head between the concave seats in the lugs 9and the shoe 8 and on these studs the conical nuts are adapted to screw.Each nut is also provided with a transverse slot 11 for the reception ofa suitable wrench.

From the construction and arrangement of parts as above described, itwill be seen that when a knife has been placed in position,with thebinder shoe bearing against one face thereof, the insertion of theconical nuts on the threaded studs between the lugs 9 and shoe 8 Willcause the latter to force the knife against its bearing on the head. Asthese nuts are turned on the studs 10 the conical l nuts will be fedtoward the head 1, thus pressing the shoe 8 against the knife and Ibinding the latter securely in place.

Slight changes might be made in the details of construction of myinvention Without l departing from the spirit thereof or limiting itsscope and hence I do not Wish to limit myself to the precise detailsherein set forth.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is

1. The combination with a cylindrical cutter head and a longitudinallydisposed knife, of bearings on the head, a longitudinally disposedbinder shoe having the bearing faces, and conical devices disposedbetween the bearings on the head and bearings on the shoe for causingthe latter to bind the knife to the head.

2. The combination with a cylindrical cutter head and a longitudinallydisposed knife, of a series of lugs on the head, a longitudinallydisposed shoe to bind the knife to the head, and conical devices betweenthe lugs on the head and the shoe.

3. The combination with a cylindrical cutter head and a longitudinallydisposed knife, of a series of lugs on the head, a longitudinallydisposed shoe to engage the knife and bind it to the head, conicaldevices between the lugs on the head and said longitudinally disposedshoe, and threaded studs secured to the head and on which the conicaldevices are adapted to screw.

4. The combination with a cylindrical cutter head and a longitudinallydisposed knife, of a longitudinally disposed shoe to bear against theknife, bearings on the head and devices having inclined faces disposedbetween the bearings on the head and the shoe to cause the latter tobind the knife longitudinally of the head.

5. The combination With a cutter head having a knife socket, and a screwsecured in the bottom of said socket, of a binding shoe for a knifelocated in said socket, and a cone threaded on said screw andcooperating with said shoe to bind the knife to the cutter head.

6. The combination with a cutter head provided with a series of bearinglugs, and

a cutter in front of said lugs, 'of a shoe bear- In testimony whereof, Ihave signed ing against said cutter, a serles of screws specification inthe presence of two subsecured to the head and disposed between soribingwitnesses.
